Meter Overview
The meter is a whole current credit meter, capable of measuring kWh and is the type approved to BS EN61036: 1996 class 1.0and 2.0. A LCD will display all the meter’s data.
Operational Requirements
Measurement
The Meter is a 220 Vac - 240 Vac, 50 and 60 Hz, 20 - 100 Amp Single Phase Credit Meter. It contains an independent measuring element allowing consumed energy to be measured. The meter measures and registers kWh to class 1.0. There is a red LED mounted on the front panel of the meter, pulsing at a rate of 1,000 pulses per kWh for energy registration.
Total kWh Register
The total kWhs measured are stored internally to 3 decimal places. The total kWhs are displayed on the meter to a maximum of 2 decimal places unless programmed via the Flag Port (see User Interfaces) to 3 decimal places for testing purposes.
- The Total kWh register range is 0 - 99999.999 kWh
Reverse Energy Register
The reverse kWhs consumed by the meter is stored internally to 3 decimal places, but only displayed to a maximum of 2 decimal places.
- The Reverse kWh register range is 0 - 99999.999 kWh
Reverse Energy Indication
If reverse energy is detected, the display alternates between a Reverse Energy Detected message and the default display.
User Interfaces
Optical Interface
The meter has a FLAG optical interface based upon the IEC 1107 protocol.
If the meter is to be programmed using a third party HHU, the HHU will possibly require modification to work with the meter. This is because the meter uses a masked processor.
Inductive Serial Data Port
The meter incorporates an Inductive Serial Data Port that will transmit all the information within the meter through the meter case. The data transmitted is generally in accordance with the CMI specification and can be received by any module fitted with a suitable receiver placed adjacent to the transmitter outside the case. (There is no physical connection)
Functional Requirements
General Facilities
The default display is always the Total kWh’s consumed.
Installation
The meter is designed to fit onto a standard meter board. Special care should be taken to ensure that the meter is installed in such away as to allow easy access for meter reading.
Mounting the meter
Using 2 off No 8 1”, screw the meter to the board via the two fixing holes either side of the terminal housing.
Connections
As per wiring diagram shown in figure 1. Terminal arrangement conforms to BS5685, Part 1, 1979.
The DIN specification wiring layout is available on request
